Rear brake flexi pipe corrosion.

[RUM4MO]

I was just servicing my older daughter's May 2019 SEAT Leon Cupra today, and while cleaning up the brakes, spotted severe corrosion on both rear brake flexis - on the rigid section at the calliper end!
So, that's stopped me replacing the brake fluid for a day or 2 until I've sourced and fitted new rear brake flexis!
I'm guessing that this is just down to a lack of corrosion protection on that short section of rigid steel pipe, not really good enough!

Has it ever been to a cheap car wash? Corrosive wheel cleaners can do a lot of damage around the brakes/dust shields/hubs etc..

Did see my pictures of my rear control arms Something is up with these MQB platform cars where the rear suffers way more from corrosion than the front Also the splash shields were pretty much gone
